Abstract: PURPOSE:To make it possible to make privacy communication by providing a sound signal transducer that makes specific signal transducing of ordinary sound signals in a voice band and makes reverse signal transducing in a mobile machine, and providing a similar sound signal transducer that can be switched and connected to a call circuit. CONSTITUTION:The classification information of a sound signal transducing system in mobile subscriber information is transferred from an MEX 2 to an RCC through a DTE 24 and a DTE 34. The RCC 35 controls the operation of an SCV 313 through the SUPC 314 of a VCR 31 and inserts a CVA 311 in the call circuit. Then, ordinary sound signals are sent to the call circuit from the MEX 2 to VCR 31, and transduced to specific signals in voice band by modulating the side of the CVA 311, and transmitted signals from a TRX 41 is modulated by the signals. On receiving this radio wave, the MS 11 of an automobile 1 demodulates the radio frequency signals and obtains specific signals within voice band. The signals are returned to ordinary voice signals by the demodulating side of a CVA 12 and received by a transmitter-receiver 13. On the other hand, the ordinary sound signals sent from the transmitter-receiver 13 are given from the VCR 31 to the call circuit of the MEX 2 through the same procedure in the direction reverse to above-mentioned.

Title: Reproducer of information disc
Inventor: SAKAI KIYOHARU
IPC: G11B17/049
Filed: 1982-07-12
Abstract: PURPOSE:To avoid any trouble such as detaching of a disc in the reproducer, by providing a buffer means absorbing a sudden application of a drive force to a part of a link mechanism moving upwards and downwards a disc holding mechanism for slowing down the descending operation. CONSTITUTION:A damper plate 100 is turned via a lifter link lever 91, a lifter link bar 93, and a lifter link lever 95 when a link slide plate 57 moves toward the arrow C to descend a disc holding mechanism A. Since the distance between rotating center shaft 101 of the damper plate 100 and a shaft 9 is comparatively short, it is required for a large moment of inertia to turn the damper plate 100, allowing to suppress the sudden rotation of the lifter link lever 95. As a result, the link slide plate 57 is moved comparatively slowly toward the C. The disc holding mechanism A is descent via the disc lifter lever 51 in response to the slow movement.

Title: Convergence correcting device
Inventor: NAKAHARA HITOSHI
IPC: G09G1/28
Filed: 1990-05-12
Abstract: PURPOSE:To save power, and to raise precision high by providing a first means to correct the large amplitude corrected component of misconvergence and a second correcting means to correct the small amplitude higher order component of the misconvergence. CONSTITUTION:The large amplitude lower order corrected component of the misconvergence is corrected by the first correcting means by superimposing the correcting current of the lower order component of the distortion of large correcting amplitude upon a horizontal and a vertical main deflecting currents to main deflecting yokes 22, 23. Then, after correction data given to a correction point obtained by dividing a display screen into lattice form is converted into analog quantity, the correcting magnetic field of only the small amplitude higher order component is generated by flowing the correcting current in subdeflecting yokes 9 to 14 by the second correcting means, and the small amplitude higher order component of the misconvergence is corrected by low power consumption. Thus, correcting power can be reduced, and simultaneously, the highly precise correction of the convergence can be executed.
